Abstract: A bed covering device provides monitoring signals responsive to movement and urination of a person lying upon a bed. The device is constructed of a fitted bedsheet having a perimeter adapted to embrace a mattress, a waterproof sheet disposed above the fitted bedsheet, moisture detectors disposed upon the upper surface of the waterproof sheet, and pressure sensors disposed upon the lower surface of the waterproof sheet. The moisture and pressure sensors generate electrical signals that can be used for monitoring or alerting purposes.

Abstract: A device for attachment to a hospital bed to facilitate the showering and/or bathing of bed-ridden patients is comprised of a compliant rectangular waterproof sheet whose perimeter has a multitude of tethers which secure the sheet tightly upon the mattress. A splash cuff is upraised from the upper surface of the sheet to retain water, and a drain port extends through the splash cuff to enable run-off water to be conveniently disposed of.

Abstract: A plastic container which confines a freezable liquid is provided with a multitude of parallel channels which permit passage of air through the container. The container is mountable upon the protective enclosure of a multi-bladed air-moving fan in a manner such that air driven by the fan passes through the channels and is thereby cooled. The container is of a small enough size to permit its storage within a residential-type freezer to freeze the liquid prior to mounting of the container upon the fan.
